本文件规定了通用位置、速度和时间（PVT）服务。它进一步规定了ITS车站（ITS-S）设施层（ISO 21217）内的PVT服务及其与ITS-S中其他功能的接口，例如: -ISO 21217中定义的ITS-S应用程序（ITS-S-APs）； -ITS车站设施层的通用设施服务处理程序（FSH）功能，定义见ISO/TS 17429。 本文件规定: -PVT服务，根据具体实施，使用各种与定位相关的源，如全球导航卫星系统（GNSS，如伽利略、GLONASS和GPS）、路边基础设施、蜂窝基础设施、运动状态传感器、视觉传感器； -一种PVT服务，用于合并上述数据- 上述定位相关源，并提供PVT输出参数（携带PVT信息），包括相关质量（例如精度）； -如何将PVT服务集成为ITS车站设施层的ITS-S能力； -PVT ITS-S功能和ITS站点架构的其他功能之间的接口功能调用和响应（服务接入点？服务原语）； -可选地，将PVT服务作为ITS-S设施层的一种能力；参见ISO 24102-6； -ASN。1个模块C-itsPvt，提供ASN。1.类型和值定义（见附录A）； -实施合规性声明形式表（见附录B），作为评估本文件合规性的依据。 注:定义相关一致性评估测试程序不在本文件范围内。

This document specifies a generic position, velocity and time (PVT) service. It further specifies the PVT service within the ITS station (ITS-S) facilities layer (ISO 21217) and its interface to other functionalities in an ITS-S such as: — ITS-S application processes (ITS-S-APs), defined in ISO 21217; — the generic facilities service handler (FSH) functionality of the ITS station facilities layer, defined in ISO/TS 17429. This document specifies: — a PVT service which, dependent on a specific implementation, uses a variety of positioning-related sources such as global navigation satellite systems (GNSSs, e.g. GALILEO, GLONASS and GPS), roadside infrastructure, cellular infrastructure, kinematic state sensors, vision sensors; — a PVT service which merges data from the above-mentioned positioning-related sources and provides the PVT output parameters (carrying the PVT information) including the associated quality (e.g. accuracy); — how the PVT service is integrated as an ITS-S capability of the ITS station facilities layer; — the interface function calls and responses (Service Access Point?service primitives) between the PVT ITS-S capability and other functionalities of the ITS station architecture; — optionally, the PVT service as a capability of the ITS-S facilities layer; see ISO 24102-6; — an ASN.1 module C-itsPvt, providing ASN.1 type and value definitions (in Annex A); — an implementation conformance statement proforma (in Annex B), as a basis for assessment of conformity to this document. NOTE It is outside the scope of this document to define the associated conformance evaluation test procedures.
